Why are some people left handed?

There are many misconceptions about people who are left-handed. It is still rare, as 10-12% of the population are lefties. Till the mid-20th century, it was common belief that left-handedness was a defect. It is in fact, left-handed people who face difficulties as the world is not designed to cater to them. A tool as common as a pair of scissors is designed to be used by right-handed people, as are certain sporting goods and most guitars!

Is left handedness determined by genetics?

Till recently it was believed that the inheritance of left-handedness was based on your parents and their genes. Research had previously focussed on the fact that your brain is the determiner for left or right handedness. However, new research suggests that the brain is not the deciding factor in the establishment of handedness.

The science of being left handed

When a child is in its mother’s womb, by 8 weeks, they have chosen a dominant hand. By the 13th week, they are either sucking their right or their left thumbs. However, it is interesting to note that it is only by the 15th week, that the motor cortex in the brain begins sending messages to the spinal cord. If the brain and the spinal cord aren’t connected in the 8th to 13th week, how did the child choose which thumb to suck? It has been suggested that gene expressions in the spinal cord lead it to make the choice, rather than the brain.

Hurricane Facts and Information

12 Interesting Facts about Hurricanes!

1. Hurricanes, typhoons and tropical cyclones are all names for the same phenomenon. They’re just called by different names in different ocean basins.
2. Hurricanes are named based on a list created by the World Meteorological Organization, used on a six year rotation.
3. If a storm is particularly destructive or deadly, the WMO will “retire” that name from official lists so it’s never used again out of respect for the families of the storm’s victims and survivors.
4. The first hurricane that caused people to fly in it, occurred in 1943 during World War II.
5. Hurricane Hunters fly planes into hurricanes to gather weather data.
6. The Saffir-Simpson Hurricane Scale defines hurricane strength by categories. A Category 1 storm is the weakest hurricane with winds having speed between 74 and 95 miles per hour; while a Category 5 hurricane is the strongest with winds greater than 155 miles per hour.
7. Hurricanes that move slowly are likely to produce more rains causing more damage by flooding, than fast moving hurricanes.
8. The eye of the hurricane is a section at the center of the hurricane which has the calmest weather with clear skies and low winds.
9. The eye is surrounded by an eyewall which is the deadliest part of the hurricane. It is a towering ring of thunderstroms, high wind speed and severe weather.
10. Planet Jupiter has a hurricane which appears as a red dot on it and it has been spinning for 300 years. This hurricane is bigger than Earth itself.
11. Hurricanes need the Coriolis Force to form – which is very weak at the Equator. This is why hurricanes can not form near Equator.
12. The deadliest hurricane on record is the 1970 Bhola Cyclone in Bangladesh, which killed between 150,000 to 300,000 people.

Did ants invent the world’s first social network?

What exactly is a social network?

Facebook, Twitter, Instagram… all these are nothing but different social networking websites. But what exactly is a social network? Just like you interact with your friends and family on a day to day basis, a social network is a platform which allows you to send and accept information. It is a web of different interactions – both social as well as personal.

Social network is not limited to humans!

Recent research has shown that the concept of a social network is not limited to us humans. Ants, through their colonies, have exhibited social behaviour, a belief which was earlier limited to humans. An ant colony is a series of complex tunnels and chambers, shared together by the colony. They use a system of chemical signals to communicate with each other. These pheromones are transferred between ants using their antennae. By doing this, they are sharing important information to help one another – to sense food, protect themselves from predators or share where they have previously been.

Communication in ants

Through the passing on of pheromones, ants are able to optimize the manner in which the colony functions. Ants in search of food for the colony have information which guides them in the right direction.

This shows us how ants created a social network long before we had Facebook!

Discovery of America

There are several beliefs in regard to who discovered America first. Most people are aware of the journeys of Christopher Columbus and how he was the first sailor to make the round trip voyage around the Atlantic. However, despite his nautical achievements, was he the first?

Who discovered America?

The most commonly known and believed story is that of Christopher Columbus – an Italian navigator and explorer who landed on the shores of ‘The New World’ in 1492. His discovery is significant as it opened up America to colonization at the hands of European powers.

History of America

However, the history of America is not as simple as that. Research has shown that Columbus was one of the last explorers to “discover” America. Almost 500 years before him, a group of Vikings, led by Leif Eriksson, landed on the shores of what is now known as Newfoundland, Canada. They did not stay for long as their relationship with Native North Americans grew hostile.

Who was the first to discover America?

A fact we often forget when investigating the mystery of who discovered America first is, that when all these different explorers came to America, there were already people there! The first settlers to come to America were in fact, immigrants. Studies suggest that Native Americans, as we know them, have genetic markers connecting them to Asian roots. During the last Ice Age, research shows that there existed a land bridge where there is now the Berring Strait – connecting Asia to North America.

There have also been claims in the past that explorers from Asia and Ireland landed on the shores of America before Columbus and Vespucci. However, these claims are still under exploration.

Moon Facts and Information

13 Interesting Facts about the Moon (Luna)

1. The moon was formed when an astronomical body about the size of Mars crashed into Earth 4.5 million years ago. This is known as the Theia Impact.
2. The sun is 400 X larger than the moon but is also 400 X farther from Earth. As a result, the sun and moon look the same size.
3. The moon is 81 X lighter than Earth.
4. The moon is slowly drifting away from Earth, approximately 4 cms a year.
5. The Earth rotates on its axis at the same speed as the moon rotates around the Earth, so we always see the same side of the moon.
6. The Moon and the Earth orbit each other.
7. The moon is not round, rather, it is shaped like an egg.
8. The moon experiences ‘moonquakes’ much like Earth experiences earthquakes. However, moonquakes can last up to an hour, unlike earthquakes.
9. The lunar maria (singular – mare) are large and dark basaltic plains on the moon made by ancient volcanic eruptions. They are known as moon seas as ancient astronomers first believed them to be filled with water.
10. An astronaut’s footprint could last for a million years, as there is no wind or water on the surface of the moon.
11. When pieces of moon rock were brought back from the Apollo 11 mission, scientists were surprised to find out they had magnetic qualities.
12. The original tapes of the Apollo moon landing were erased and re-used by accident.
13. The Moon takes 27.3 days to rotate on its axis and the same amount of time to complete one revolution around Earth. To us Earthlings, it may look like it isn’t rotating at all! Scientists call this synchronous rotation.

How Do Birds Find Their Way Home?

Did you know that almost 40% of the species of birds in the world practice migration on a regular basis? As amazing as this statistic is, what is even more interesting is the different tools that birds use to navigate during these migrations!

A migratory bird does not have a map it can use to find its way nor can it stop and ask for directions. Then how is it that at least 4,000 birds on Earth successfully migrate each year?

How do birds navigate?

There are several tools a bird can use to navigate itself to ensure it gets home safely. Birds are able to use the sun in order to have a sense of the time of the day and even nocturnal birds use the setting sun to guide themselves. Since nocturnal birds do not have the option of the sun as a reference through the night, they instead use the stars to guide themselves.

How do birds use the magnetic field of the earth?

Certain birds also have a trace amount of the mineral ‘magnetite’ in their beaks. Magnetite works like a bird’s compass, aligning itself with Earth’s magnetic field to help them gauge the direction of Earth’s magnetic poles.

Why don’t migrating birds get lost?

Birds also use familiar landmarks to help navigate themselves – such as mountain peaks, valleys, rivers and roads. Scientists have continued their research into the field of migration and migratory patterns in birds to try and also look at the role of a bird’s sense of smell in their navigation systems.

Mulla Nasruddin and the People's Judgement

One day, Mullah Nasruddin and his son were travelling to the next town. Nasruddin preferred to walk while his son rode the donkey. On the way, they passed a group of bystanders, and a man remarked, “Look, that selfish boy is riding on a donkey while his poor old father is forced to walk alongside. That is so disrespectful. What a horrible and spoiled child!”

Nasruddin’s son felt embarrassed, so he got off the donkey and asked Nasruddin to get on it instead.  His son started walking beside him and the donkey. Soon they passed another group of people. “Oh, that’s detestable!” one of them exclaimed. “That poor young boy has to walk while his abusive father rides the donkey! That horrible man should be ashamed of himself for the way he’s treating his son. What a heartless parent!”

Nasruddin was upset to hear this. He wanted to avoid anybody else’s scorn, so he decided to have both himself and his son ride the donkey at the same time. As they both rode, they passed another group of people. “That man and his son are so cruel,” one bystander said. “Just look at how they are forcing that poor donkey to bear the weight if two people. They should be put in jail for their despicable act. What scoundrels!”

Nasruddin heard this and told his son, “I guess the only way we can avoid being ridiculed by anyone, is for both of us to walk.”

“I suppose you are right,” the son replied.

So they got off the donkey and continued on foot. But as they passed another group of people, they heard them laughing. “Ha, ha, ha,” the group laughed rudely. “Look at those two fools. They are so stupid that both of them are walking under this scorching hot sun and neither of them is riding the donkey! What morons!”

Moral – Well, If you keep doing what other people want, neither would you be happy nor will they stop judging you.

Discovery of Allergies

What are allergies?

Allergies are one of the most common diseases experienced by people. It is a chronic disease – it lasts a long time or happens very often. An allergic reaction occurs when the body overreacts to a foreign substance which it deems harmful. These substances, which cause allergic reactions, are called ‘allergens’. The body’s reaction to allergens is to produce an antibody called ‘immunoglobulin E’ (IgE). The symptoms which come about as a result of the reaction between allergens and IgE are called an allergic reaction.

Types of allergies

The human body can react to a variety of allergens, which can come most commonly in the form of food (most commonly nuts), the air (pollen and dander), insect venom allergies (bee stings). However, this list expands to include a variety of other allergens. Symptoms of an allergic reaction include asthma, rashes, hives, swollen lips, amongst others.

Who discovered allergies?

The first mention of allergies came in the writings of the ancient Greek physician Hippocrates. He wrote of the negative effects which certain foods have on people. Though he did not coin the term ‘allergy’, he was the first person to recognize the fundamentals of food allergies.

The word ‘allergy’ was coined by Viennese doctor Clemens von Pirquet in 1906. This came about after he noticed that some of his patients had hypersensitive reactions to certain foods and pollen – which would otherwise be seen as harmless.

Another breakthrough was the discovery Dr. the antibody ‘immunoglobulin’ in 1966-67 by Dr. Kimishige Ishizaka in Denver, Colorado and Gunnar Johansson and Hans Bennich in Uppsala, Sweden.

How does a bicycle stay upright?

Scientists have been fascinated by the science of how a bicycle stays upright for almost as long as bicycles have existed! There are several contributing factors which aid our ability to remain upright while riding a bicycle.

How does a bicycle work?

Bicycles function through the conversion of muscular energy (energy created by the cyclist peddling) into kinetic energy (energy created by movement). The bicycle itself has several components which are simple machines – a combination of levers, pulleys and wheels and axles, which help convert the action of pedalling into movement. This may answer any confusion as to how bicycles work, however, does not address how exactly it stays upright.

Gyroscopic Effect

Till a few decades ago, scientists believed that bicycles remained upright owing to the ‘Gyroscopic Effect’ – which means that a spinning wheel will stay aligned to its original direction during motion. The momentum, in this case, is an Angular Momentum, created when a cyclist pedals and propels the bicycle forward. Though the Gyroscopic Effect explains how a bicycle remains stable, experiments conducted revealed that even if the Gyroscopic Effect were to be cancelled, the bicycle would still remain upright!

Caster Effect

The Caster Effect is another effect in play which helps guide the front tire of the bicycle in order for it to stay upright. The centrifugal force of the back wheel also plays a part in ensuring the bicycle does not fall over.

Why does a bicycle stay upright?

A bicycle stays upright due to a combination of different effects – Gyroscopic as well as the Caster Effect. Alongside this, the rider must be taken into consideration. Our mind also plays a role in making sure we do not fall over while riding a bicycle. The body unconsciously balances itself whenever it is needed. If we feel a tilt to the left, we automatically balance ourselves, by leaning into the right.

Avoid Biting your Nails!

Why do we bite our nails?

The habit of nail biting or ‘onychophagia’ could develop because of many reasons. You may notice that this habit is one seen in both children and adults. There are many causes for this habit to grow. People sometimes bite their nails when they are feeling nervous, worried, lonely or bored. They do not realize when they are chewing their nails as it becomes such a natural action. You may notice that you bite your nails more before or during exams or when you are feeling upset.

Why is biting your nails a bad habit?

Biting your nails is an unhygienic habit for many reasons. Your finger nails contain many germs which enter your stomach when you chew or bite on your nails. Biting your nails or pulling on the skin around them could also damage your finger tips or cause your nails to regrow unevenly. This habit could also lead to an infection on your finger tips and cause damage to your teeth and jaws.

What can we do to stop biting our nails?

The first habit you must develop is to keep your nails cut short and keep your hands clean. There are many things you can do every time you feel the need to bite your nails. You can play with a stress ball or stroke a smooth pebble to help deal with feelings of anxiety or stress. You can also stop yourself from biting your nails by painting your nails with bitter tasting nail polish or by wearing a pair of gloves on your hands.

Discovery of Laser

What is a laser?

The full form of ‘laser’ is actually ‘Light Amplification by Stimulated Emission of Radiation’. Did you know that we use lasers every single day? We use laser printers in offices, lasers to scan the barcodes on products when we buy them and doctors use lasers in life-saving surgeries! But have you ever stopped to wonder exactly what a laser is and how it works? The light that we see around us is a mixture of beams at different wavelengths. Together they can be seen as ‘White Light‘, which is colourless. Lasers, unlike natural light, do not occur in nature and are a creation of man. Scientists figured out how to artificially create this special kind of light.

How can laser light cut through solid objects?

A laser cannot be simply defined as a very strong torch. Lasers produce a narrow, intense beam of light, which is strengthened using a curved mirror. Unlike the light we see around us, the light from a laser consists of rays which are all at the same wavelength. Owing to this property, the waves of light in a laser travel in phase (with their peaks lined up). It is able to cut through things because of this intensity and the fact that it can be focussed into a very tiny spot. It is different from a simple beam of light in many ways. A laser is ‘monochromatic’- only of one colour. This is because all the light in a laser beam is of the same wavelength. The rays of light in a laser are also ‘collimated’ – they can travel in beams parallel to each other, which allows them to travel in a straight beam for long distances. Lastly, the light is ‘coherent’, meaning that it moves in phase together.

Do fish sleep?

Imagine a fish swims all day long. It must get really tired and probably just wants to have a shut eye. But how? Most fish have no eyelids.

Eyelids help terrestrial animals keep their eyes moist. But since fish are always underwater, they do not need eyelids to help keep their eyes moist.

So it’s really difficult for us to make out, if they are sleeping or not!

So if fish don’t have eyelids, does this mean they do not sleep?

Almost all fish sleep. Though some zebrafish are insomniacs. Which means they have trouble sleeping!

Do fish lay down to sleep like other animals?

Since fish live in an environment unlike ours, laying down and sleeping like humans can be dangerous. They rest their brains in parts at different times and are never completely unconscious.

How do fish sleep?

Some fish like the shark keep swimming in their sleep. Tuna fish rest motionless at night, suspended in the water. Bass and perch will sleep under or on top of logs. Reef fish seek refuge in crevices. Parrotfish build a cocoon of mucus in which to sleep.

Why is sleep and resting our body so important?

If we do not sleep properly, we will always be tired, cranky and unhappy. This is because when we sleep, the body also gets a chance to clean itself of waste and other by-products of cell functions within our bodies.

So, fish also need to sleep, so that they can repair their cells and also conserve their energy.

Being responsible with money!

Where does money come from?

Who doesn’t love to get a toy that they were eagerly awaiting or a nice pair of shoes? But have you ever wondered where does money come from? From our parents? How do they get it? From the ATM? From the bank? Well, they work very hard for it and bank just keeps them safe.

How can you be responsible with money?

You can get all you want if you plan the way you want to spend the money that your parents give you.

Make a wish list –

1) Make a wish list which will have all the items that you want for yourself.

2) Rank them in order of what is the most important item for you.

3) Spend money on the items that are ranked higher on the list.

How to save money?

Don’t spend all the money you have as soon as you get it. Create a budget, spend it only on the items that are top ranked on your wish list. Set aside the remaining money (in your piggy bank!).

Once you save enough money, spend it on the rest of the items you have mentioned in your wish list. This way you will get all that you want. Money can be used not just to buy things you like but also to help people. You can always donate a portion of your allowance to a charity that is important for you (like helping hurricane survivors!)

Discovery of Ozone

What is ozone?

Ozone is a highly reactive gas made of three atoms of Oxygen. It is produced naturally when the sun’s rays split oxygen molecules. The free atoms combine with nearby oxygen molecules to form a three oxygen molecule, known as Ozone. This occurs in the Stratosphere and Troposphere layers of the atmosphere.

When was ozone first discovered?

Ozone was first created in a lab by the Dutch chemist Martinus van Marum, in 1785.

Health and environmental effects of ozone

The Ozone in the Stratosphere protects us from the harmful ultra – violet rays of the sun. The Ozone in the Troposphere layer of the atmosphere contributes to air pollution, damaging life forms including causing several breathing problems to human and animals.

Mullah Nasruddin: What clever people do?

One fine morning, Mullah Nasruddin was wandering around a lake. The cool breeze was creating ripples on the surface of the water. Green grass and algae grew on the fringes of the lake. The air was filled with birds chirping.

Mullah Nasruddin sat down beside the lake, enjoying nature around him. He collected small pebbles around him and started tossing them in the water, causing more ripples in the water. The fish in the water darted around, trying to avoid the pebbles. Mullah was lost in thought, when he heard ducks quacking. He looked up to see a flock of ducks swimming close by in the lake.
Mullah thought to himself, “It would be nice to catch a duck or two for dinner.”

He got up and started wading in the water to get closer to the ducks. Mullah was very excited, as he thought about the duck soup he was going to enjoy. The ducks saw Mullah approaching and moved away. But, Mullah kept moving towards them, determined to have his duck and eat it too!

Mullah lunged towards them and the ducks flew away. A surprised Mullah slipped and went under the surface of the water. As he tried to gulp in some air to breathe, he gulped in water, instead. He finally emerged out of the lake, coughing and sat down on the shore.

he was determined to try to catch a duck or two, again. Even though I have failed the first time, I will try again. I shouldn’t lose hope. But the ducks were more cautious this time and had a different plan.

All the ducks were gathered at the centre of the lake and were not moving an inch. As Mullah Nasruddin had no option, he got into the lake and moved to the centre of the lake. But then, the ducks moved to the opposite corner. After several failed attempts, he got tired, and lay down on the lake side, to dry himself off and catch his breath.

After some time, he got up He sat down, by the lakeside again and opened his bag and took out a roll of bread. He dipped the bread in the water and began to eat it.

Some people from the village close by were walking past the lake when they saw Mullah dipping his bread in the lake and eating it.

A man asked, “Mullah, what are you doing?”

Mullah replied, “I am having Duck Soup.”

The man looked at Mullah asked bemused, “Duck Soup?”

The people in the crowd looked at each other. Mullah looked at their confusion and laughed and answered, “That is what clever people do. One who accepts what he or she has, is always happy.”

What came first, the fruit or the colour Orange?

What do you think of when you hear the word ‘orange’?

Do you think of the colour, or the fruit?

Do you imagine the vivid, sweet citrusy fragrance and tangy taste of the fruit, or do you see the colour and its myriad shades?
Don’t you think its fun to eat a colour? No, you aren’t really eating the colour!

Origin of the word orange

The word orange did not exist in the English dictionary till 1300s. So what did people refer to when they wanted to refer to the colour orange? They called it geoluhread or yellow – red. Till some one decided to call the colour orange, ORANGE colour!

Wow! Wonder how he did that? Do you think he saw the exotic fruit and thought, hmm, it reminds him of the colour yellow – red.
But first, let’s see where the fruit’s name originally came from.

What was the colour orange called before oranges?

The fruit’s homeland is in India. The Indians referred to it as narange or naranga, which may have its root in the word for smell in Dravidian languages. The fruit travelled to Europe with Indian, European and Arab traders. The Arabs refer to it as burtakal, which originates from the word for Portugal and the Persians refer to it as naranje.

The word naranje probably worked its way to into the English dictionary from the French, who called it pomme d’orange. The english simplified the word to simply call it orange, in the 1500s.
In 1600s, someone decided to adopt the name of the fruit to the colour, they have previously referred to as yellow – red.

Did the colour orange come before the fruit?

So, now you know, what came first. The fruit ofcourse, and the colour is named after the fruit.

The fruit came first.

Poet, clown and jester… Tenali Raman was a minister in the court of Krishnadevaraya, the ruler of Vijayanar. He was an extremely versatile personality. The entire kingdom always buzzed with the news of his stories and practical jokes.

He was very famous and stories of his wisdom spread beyond Vijaynagar, in cities which are a part of Karnataka and Tamil Nadu now. A great scholar by profession, Tenali Raman also knew several languages.

There once lived a man called Ramaya in the town of Vijayanagar. It was believed that whoever saw the face of Ramaya the first thing in the morning, would not be able to eat anything throughout the day. So, all the people of Vijaynagar avoided Ramaya all the time.

The news also reached the king’s ears. He wanted to find out the truth for himself and called for Ramaya at once. He made Ramaya stay at a room adjacent to his bed chamber for one night.
The next day, when the king woke up, he went and saw Ramaya’s face the first thing the morning.

Later in the afternoon, the king sat to have his lunch. He was served with freshly cooked hot food. As he was about to take his first bite, he noticed that there was a fly in his food. He threw away the platter and ordered for fresh food. But by the time the food was cooked for the second time, he was not hungry any more.

Thus, the king realized that whatever the people said were true, Ramaya was indeed jinxed. So he ordered his soldiers to hang him immediately.

The soldiers did not want to hang him, but they could not go against the king’s words. They were taking Ramaya towards the gallows, when they met Tenali Raman on the way. Tenali whispered something in Ramaya’s ear and then Ramaya was whisked away by the soldiers.

Later, when the soldiers asked Ramaya about his last wish, he said that he wanted to send across a message to the king. He requested them not to hang him until he received the response of the king.
He said to the soldiers, “Go and tell the king that if it is true that anyone who sees my face in the morning loses his appetite for the day, then anyone who sees the king’s face in the morning is destined to lose his life that day. Tell him that if I am jinxed then so is he, and in fact more than me.”

The king was speechless when he heard Ramaya’s message. He ordered the execution to be stopped immediately. He was ashamed of his ignorance. At once he called Ramaya and offered him a lot of gifts and also requested him to not disclose this incident to anyone in the town.

After all, the people of Vijaynagar would not like to be ruled by a man who was jinxed.

Mullah Nasruddin and The Guest of Honour

It was a busy day in the village. Mullah Nasruddin was out for his evening stroll, with his donkey, when he chanced upon a huge gathering of people outside the town hall.

He turned to a person in the crowd and asked him. “What is happening here?”

The person replied, “I don’t know, but some very important people from all over the country and some neighbouring countries have also come.”

“Oh!”, exclaimed Mullah, “Let me find out.”

Mullah Nasruddin walked to the entrance and tried to enter unnoticed.

The guard standing at the town hall’s big doorway stopped and asked him, “Sir, please let me know your name. I cannot allow common people to enter. Some very important people have come here today.”

Mullah looked at the guard and said, “Sir, I am here to deliver an important message for some very important people.”

The guard looked at Mullah Nasruddin suspiciously.

“Sir, please let me in. It is an important message and I cannot tell you whom it is for.”

“No sir, I cannot allow you inside, without knowing whom you want to meet”, replied the guard.

“Sir, please let me in. I will only go inside for a few moments and come out. Here, you can hold my donkey, while I go in.” answered Mullah.

Reluctantly, the guard allowed him inside.

Mullah Nasruddin entered a formal reception area and seated himself at the foremost elegant chair.
The Chief of the Guard approached and said: “Sir, those places are reserved for guests of honour.”

“Oh, I am more than a mere guest,”replied Nasruddin confidently.

“Oh, so are you a diplomat?”, asked the Guard doubtfully.

Answered Mullah, “Far more than that!”

“Really? So you are a minister, perhaps?” the Guard asked again.

“No, bigger than that too”, replied Mullah.

“Oho! So you must be the King himself, sir?” asked the Chief sarcastically.

“Higher than that!” asnswered Mullah, cheekily.

“What?! Are you higher than the King?! Nobody is higher than the King in this village!”

“Now you have it. I am nobody!” said Nasruddin.

Moral of the story – “One cannot be successful or happy in life without a humble but reasonable confidence in oneself.”

Tenali Raman : Tenali Raman and The Arab Horse Trader

Once, an Arab horse trader came to Krishan Deva Raya’s court.

He said, “Your Majesty, see this Arab steed! It is my finest. If you like, I can get more.”

Krishna Deva Raya replied thoughtfully, “This is the only breed missing from my stable.”

The king saw the beautiful horses standing outside his palace.

Krishna Deva Raya said impulsively, “I will buy them all!”

The trader replied, “I need an advance of 5000 gold coins. I’ll bring them in two days.”

Two weeks passed.

Krishna Deva Raya thought to himself while walking in his garden, “Where is the trader?” He saw Tenali Raman sitting there, writing on a piece of paper.

Krishna Deva Raya asked, “What are you writing, Tenali Raman?”

Tenali Raman replied, “I’m listing the biggest fools in the land.”

Curious, Krishna Deva Raya said, “Let me have a look.” Tenali Raman handed him the paper.

Krishna Deva Raya was taken aback and angry. “How can my name be at the top of this list? I’m the king!”

Tenali Raman retorted, “Whoever gives a stranger 5000 gold coins and thinks that he will return is a fool, Your Majesty.”

Krishna Deva Raya asked, “What if he returns?”

Tenali Raman replied in an instant, “Then I will put his name at the top of the list instead of yours!”

Krishna Deva Raya said, “I understand what you’re saying, Tenali. I will always consult you now on important matters.”

Return things you have borrowed from others

Why is it important to return things that you have borrowed?

A lot of us have favourite things, objects or books or clothes or toys we have collected or found or saved for special occassions. Some times it’s a present from some one we love a lot, or sometimes a favourite relative thought of you and brought it from some place they travelled to. Which means they thought you were special.

What happens when someone borrows it and doesn’t give it back, or damages it or breaks it?

You get upset. The same way, your friend may also get upset, if you don’t return their things. Your friend must like you a lot, if they have shared something with you. You must always remember to return it. It shows we like the friend or relative and we value them in our lives.

It is called good manners or good social etiquettes.

Conditional Clause and Its Types

What is a conditional clause?

Conditional clauses are also called conditional sentences. They always have two parts, a main clause and an ‘if’ clause, which is a condition or a suggested situation.

Example: If he studies, he will pass in his exams.

Why is an ‘if’ used in a conditional clause?

An ‘if’ is used in a conditional clause because a conditional clause can only take place if a certain condition is fulfilled.

Types of conditional clauses

Conditional clauses are of the following types :

1. Zero conditional clause

In a zero conditional clause, general statements are used about actions that are certainly happening. Both the clauses are in present tense.

Example: The water boils, if it is heated

The water boils – Main Clause in Simple present
if it is heated – Conditional Clause Simple Present

2. First conditional clause

In a first conditional clause, the main clause is in the future and the ‘if ‘clause is in the present tense.

Example: If you don’t leave early, you will be late for school.

If you don’t leave early – Conditional Clause in Present Tense
you will be late for school – Main Clause in Future Tense

3. Second conditional clause

In a second conditional clause, past tense is used in the ‘if’ clause and the conditional perfect in the main clause.

Example: If I could cook, I would make a vegetable curry.

If I could cook – Conditional Clause in Past Tense
I would make a vegetable curry – Conditional Perfect in Main Clause

4. Third conditional clause

The third conditional clause uses a past tense in the ‘if’ clause and the action in conditional perfect.

Example: If he had known, he wouldn’t have done it.

If he had known – Conditional Clause in Past Tense
he wouldn’t have done it – Main Clause in Conditional Perfect

Simple Exercises:

Fill in the blanks with the right conditional to complete the sentence.
1. If you help your sister, she _________ be happy. (will)
2. If we ___________ a car, we could travel more. (had)
3. The baby __________ sleep, if we keep quiet. (will)

Mullah Nasruddin and the Trial

Mullah Nasruddin’s wife was worried that her husband didn’t earn a living. This caused her a lot of stress. She thought her husband, like other husbands should work and earn a living for the family.

As she usually did, she started questioning the husband again, which soon became an argument.

Wife angrily said, “Why can’t you be like normal husbands and do some work and earn a living?”

“Dear Wife, I am worker of the Almighty God. How can I do another job?” replied Mullah.

“Dearest Husband, maybe you can then ask your God to give you something in return for your service,” retorted his wife.

Answered Mullah calmly, “Dearest Wife! You are right. I hadn’t thought of asking God for any returns for my service. Maybe that’s why he doesn’t give me anything.”

“Ohh, then please go and ask your almighty God for some return for your service”, the wife grumbled.

Mullah Nasruddin went to the garden near his house. He sat down on the ground and opened his arms, looking towards the sky.

He said loudly, “Oh God, since I am your humble and devoted servant, will you give me a 100 gold coins for my devotion towards you?”

Mullah’s neighbour, Ahmed was in the balcony and he heard this. He decided to play a prank on Mullah. He threw a bag full of 100 gold coins towards Mullah.

A shocked and surprised Mullah opened the bag to find a 100 gold coins in the bag. He got up and went home with the bag. He called his wife and showed her the bag and said, “See! I am such a good devotee of the Almighty that he gave me a 100 gold coins.”

His wife happily took out a coin from the bag and went to the market.

Seeing Mullah’s wife shopping, their neighbour Ahmed’s wife, grew suspicious. She had a word with Ahmed about this. Ahmed stormed into Mullah Nasruddin’s house and angrily demanded his 100 gold coins back. Mullah remarked back, “How dare you ask for my gold coins? I know you overheard me when I asked the Almighty God for the gold coins.”

“I should sue you in court for justice” an angry Ahmed replied.

Mullah pleadingly, “My friend Ahmed! I am a poor man. I don’t have any good clothes or even means to travel. The judge will surely trust you more.” A resigned Ahmed, gave Mullah Nasruddin his jacket and horse too! They went to the court.

At the court, the judge listened to Ahmed’s complaint. He turned to Mullah and asked him, “Do you want to say anything?’

“My neighbour Ahmed is completely mad”, replied Mullah.

The judge asked Mullah if he had any proof.

“Yes”, replied Mullah.

“Well he assumes, everything I own is his. First it’s the gold coins, then it’s the jacket, then it’s the horse,” replied Mullah.

The judge asked “Is this true Ahmed?”

Ahmed was very upset and angry on hearing this. He replied angrily to the judge, “Yes!”

The judge looks at both of them and said, “There is no point to Ahmed’s complaint. You can both leave.”

Well now, do you think Ahmed’s prank on Mullah was worth it?

Discovery of Genetics

What is Genetics?

The study of genetics is a fascinating science and a useful one. It is the study of genes, genetic variation and hereditary characteristics in living organisms.

Who discovered Genetics?

Gregor Mendel is considered the father of genetics. Mendel studied ‘trait inheritance’, patterns in the way traits or characteristics are handed down from parents to offsprings. The units of inheritance are referred to as gene.

The genetic make up is what makes a person unique.

Subsequent research and study in genetics have helped us to understand chromosomes, mutations, DNA and understand evolution better.

London Eye Facts

What is the London Eye?

The London Eye is the world’s tallest cantilevered observation wheel, on the South Bank of the River Thames.

It was formerly known as the Millennium Wheel or the revolving observation wheel.

What is the height of the London Eye?

At a height of 443 feet(135 meters), the London Eye was the world’s tallest cantilevered observation wheel, before it was surpassed by the Star of Nanchang, in Nanchang, China.

Who built the London Eye?

The London Eye was originally conceived by David Marks and Julia Barfield of Marks Barfield Architects in 1993, in response to a competition organised by the Sunday Times and Great Britain’s Architecture Foundation.

How long did it take to build the London Eye?

London Eye was constructed over a period of two years. Construction began in 1998 and it was inaugurated by the British Prime Minister, Tony Blair on December 31, 1999.

It admitted its first paying passenger until March 9, 2000.

4 Fun facts about the London Eye

1. The 32 capsules on the London Eye are representative of the 32 London boroughs and each one weighs as much as 20,000 pounds, approx But they are numbererd 1 to 33, avoiding the unlucky number 13.
2. The London Eye can carry 800 people each rotation.
3. The capsules travel at a pace of 26 cms per second, which is really slow.
4. The London Eye is not a ferris wheel, as it is supported by an A frame on just one side, and the carriages are outside the wheel rim instead of hanging low.

Here’s another great story about Tenali Raman.

Once, king Krishna Deva Raya wanted to expand his army. So, he needed more horses. He decided to give one horse to each person in his kingdom, to take care of. He also gave everyone a good supply of straw to feed the horses. Everyone except Tenali Rama was happy with this plan. He shut his horse in one room and everyday at exactly nine o’clock he gave the horse very little straw through the window. He gave the rest of the straw to his cows who became fat and healthy.

At the end of a year, the king wanted to see all the horses. All the people who had been given horses to grow up, brought their horses for inspection. But Tenali Rama did not bring his horse. On being questioned, he answered that his horse had become so strong that he could not bring it to the court. The king was surprised on hearing this. He said, “Alright, I will send my chief inspector to your house tomorrow morning at nine to inspect the horse there.” Tenali agreed.

The next morning, the chief inspector went to Tenali’s house. He had a long beard. Tenali took him to the room where the horse was kept and asked him to look through the window. When the inspector peeped through the window, naturally his beard went in through the window first. Seeing the beard, the horse thought that it must be straw that was being given to him at the fixed time. It caught hold of the beard in his teeth and pulled. The inspector shouted in pain and tried to pull his beard back. But the horse knew that this was the only food he would get all day and pulled with all his might till the inspector lost his beard.

The inspector went running to the king. He reported that indeed Tenali Rama’s horse was the strongest of them all.

Be Nice, Ask for Permission!

Everyone is a bit inquisitive. Sometimes we go to a friend or a relative’s house. We play, we jump, we take things, even open cupboards and play inside or we may even try out clothes or shoes! Sometimes we even open the fridge and may even drink water or juice.

But wait.

Did we ask our friend or relative, if we may touch or play with their things? To ask to use or touch something, or even enter a room is called Asking for Permission. Sometimes people don’t like it and may even get upset, if you touch their things. Your friend may even fight with you and not speak to you. Because they may feel they are being taken for granted.

Asking for permission is social etiquette

Do you remember, we learned about social etiquette and that we must say please and thank you? Well, asking for permission, before we touch or use something that doesn’t belong to us, is also social etiquette.

So, remember to ask for permission the next time!

What are Powers and Roots?

What is the power of a number

When a number is multiplied by itself either once or several times, the number of times the number is multiplied is known as the power of a number.

Example –
a) Multiplied by itself
5 x 5

b) Multiplied by itself multiple times
3 x 3 x 3

We can also write these numbers in a different way.
5 x 5 = 52
Or
3 x 3 x 3 = 33
Or
6 x 6 x 6 x 6= 64

What is an exponent, base and power in a number?

  • The small number at the top is the exponent. It is how many times the number is multiplied by itself.
  • The large number is called the base. It is the number that is being multiplied by it self.
  • The power of the number is how many times the number is being multiplied by it self.

How is the power of a number calculated?

The power of the number : 64 is
6 x 6 x 6 x 6 = 1296

The power of the number 72 is
7 x 7 = 49

What is the root of a number?

The root of a number A is another number, which when multiplied by itself a given number of times, equals A.
a) 5 x 5= 25
The number 5 is the root of twenty five.

b) 6 x 6= 36.
The number 6 is the root of the number 36.

How to calculate the root of a number?

Find the root of the number 16 :

Method –
16 is a small number – so it will be easy to figure out by multiplying small numbers by themselves:

1 x 1 = 1
2 x 2 = 4
3 x 3 = 9
4 x 4 = 16

So the root of the number 16 is 4.

Mullah Nasruddin at Tea Shop

Mullah Nasruddin was sitting at his favourite tea shop and having his daily tea.

A twelve years old boy, came running through the door, and went directly towards the Mullah and knocked his beautiful cap off his head. The mischievous boy ran away, leaving Mullah surprised. Mullah Nasruddin remained quiet about the boy’s prank. He picked up his cap, and put it back on.

The next day, the same thing happened again. Mullah didn’t react this time either. Although this happened several times, Mullah Nasruddin remained unaffected. The boy thought his prank was amusing and repeated it daily. Mullah would patiently dust his cap and put it back on, every time.

One day, Mullah’s friend questioned him about the daily incident. “Why don’t you punish that naughty boy? He is behaving so badly with you. How can you not get angry?”

“It is useless,” Mullah replied.

One day, Mullah reached the tea shop a bit late. When he reached there, he saw a tall, well built soldier sitting at his favourite place already. Wishing to avoid trouble, Mullah sat on another chair.

In a while, the mischievous boy appeared and ran straight to Mullah’s usual place. He knocked his cap off his head and started to run away. The poor unfortunate boy, in his hurry didn’t realise that it was the soldier and not Mullah Nasruddin, having tea. The soldier spilt his tea and got angry. He caught and lifted him.

Mullah Nasruddin turned to his friend and said, “Now, do you understand, why I was patient?”

It’s always better to Wait for the right time!

Aerodynamics of Paper Planes

A simple piece of paper will fall down when dropped, but if we fold the same piece of paper in a specific manner, it will fly.

How do paper planes fly?

The ability to fly means the ability of an object to move or travel through air. There are four things that decide if an object is going to fly or not. Any change in these same factors also decide how fast it will fly or how fast it will fall.

What are the forces that prevent an object from flying?

Forces that prevent an object from flying are :

  • The weight force downwards: The heavier the object, the greater the force of gravity that pulls it down. That is why when we want to make things fly, we make them as light as possible. This is how weight affects the flight of the airplane.
  • The drag force: Drag is the force that is exerted in the opposite direction that the object is pushed in. It increases as the speed increases. In airplanes, drag is caused by the air surrounding the airplane.

The field which studies the interaction between the air and the moving object is called aerodynamics. The study of aerodynamics is important when designing airplanes and other objects moving through the wind. It is even used when designing trucks and trains.

  • The thrust upwards: The thrust upwards has to always be more or equal to the thrust downwards or the object will fall down. In airplanes when the plane moves in the air, the wing is designed in such a way that the air it is cutting through, is pushing the plane up. In helicopters, the thrust is generated by rotor blades that push the air downwards like a fan.
  • The thrust forward: The thrust forward pushes the plane forward. This pushes the airplane in a given direction. If the thrust forward is more than the drag force, the plane increases in speed. If the thrust is less then the drag, the plane decreases in speed. In large airplanes both thrust and force is generated by propellers or jet engines.

How far do paper planes fly?

The current world record for the distance a paper plane has flown is around 225 feet! Not bad for a folded piece of paper!

Discovery of Gold

What is gold?

Gold, a shiny metal is also known as a noble metal. It has been revered since time immemorial to be fit for kings and god and rightly so!

It is one of the most ductile and malleable metals and substances known to man. It is also resistant to tarnishing and maintains its original structure even under the most severe chemical stress.

Who discovered gold?

According to ancient Greek legends, there is proof that gold existed and was known to the Greeks of the Chalcolithic (5000 BC) period, also known as the early Bronze Age. They had even devised methods of refining and extracting gold from ores, including a smelting process called ‘Fire Sitting’. Later Greek geographer Strabo (64 BC – 24 AD) makes a mention of this in his works.

The early Romans from around the same time period, also had a fascination for gold and infact expanded their empire, to get more gold. They had improvised on physics to make a hydraulic gold mining machine.

The ancient Egyptians also have records of their gold mining sites in Nubia in the Turin Papyrus Map, one of the oldest topographical maps discovered.

When and where was gold discovered?

Gold objects have been found in several burial sites or old civilisation of the same time. The oldest known gold objects were discovered by chance, by a Bulgarian excavator operator, Raycho Marinov, in 1972. The ancient burial site, Varna Necropolis, dates back to 4560–4450 BC, according to carbon dating conducted in 2006.

Perpendicular Bisector: Definition & Theorem

What is a perpendicular bisector?

A perpendicular bisector of a line segment is a line that passes through the mid point of the line segment and is perpendicular to the line.

How do you draw a perpendicular bisector?

To draw a perpendicular bisector you need the following things :

  • Compass
  • Sharpened Pencil
  • Ruler

Instructions :

  1. Draw a line of any length on a piece of blank paper.
  2. Insert the pencil in the compass and extend the compass so its points are more than half the length of the line.
  3. Put the pointy end of the compass down on one end of the line segment, then use the pencil inside the compass to draw an arc over the midpoint of the line segment on both sides of the line segment.
  4. Now, keeping the compass exactly the way it is, put the pointy end down on the other end of the line segment and draw two more arcs over the midpoint. You will see on both sides of the line: the arcs will intersect.
  5. Then take a ruler and draw a line between the two intersecting points that will pass through the line segment. This line is your perpendicular bisector.

Perpendicular bisector of a triangle

Perpendicular bisectors of triangles are drawn at each side of the triangle. Thus each triangle has three perpendicular bisectors. The point where the perpendicular bisectors of the triangle meet is known as the circumcenter of the triangle.

Perpendicular bisector theorem

  1. The theorem states that if a point is on the perpendicular bisector of a line segment, then that point is at an equal distance from both endpoints of the line segment.
  2. The converse of the perpendicular bisector theorem states that if a point is at an equal distance from both ends of a line segment, then that point lies on the perpendicular bisector of that line segment.

Why are perpendicular bisectors useful?

Perpendicular bisectors are useful in geometry, if we want to find a mid point of distances. This is necessary in architecture and study of mechanics and machinery and their construction.

Here’s another great story about Tenali Raman.

Once, a great pundit from a foreign land visited King Krishna Deva Raya’s court. He claimed that he had knowledge of all subjects and was an expert in every field. He challenged that he would argue with all of his wise ministers and defeat them. The king accepted his challenge. The pundit then proceeded to argue with the learned men of the kingdom on various subjects. The king’s ministers failed miserably. Then, the king summoned his wisest minister, Tenali Raman.

Tenali took a small bundle from his home, gave it the shape of a book and tied it up. Then, he went to the court and announced that he was ready to argue against the pundit but on the condition that the topic of their debate would be based on the great book ‘Thilakashta Mahisha Bandhanam.’ The great pundit was stumped when he heard this because he had never heard of any such book. He asked the king to give him one night’s time to prepare for the argument. He was sleepless all night. He could not bear the thought of losing so he took all his belongings and left the city before sunrise. He left a note for the king saying that he had never heard of the great book.

The next day, at the appointed time Tenali appeared in court for the debate. But he was informed that the pundit had already gone away. The king being a learned man wanted to read the great book that Tenali had mentioned, so he asked Tenali about it. Tenali laughed and replied that there was no such book called ‘Thilakashta Mahisha Bandhanam’. Inside the bundle, there was til which is called Thila in Sanskrit and some sheep dung which in Sanskrit is known as Kashta. These contents were tied by a rope made of buffalo’s hide which is called Mahisha. Bandhanam refers to ‘tying’ in Sanskrit.

This is how Tenali tricked the pundit into believing that there was a great book that the pundit was completely unaware of. The king appreciated Tenali’s intelligence and rewarded him.

Who decided a year should have 12 months?

People across the world follow the Gregorian calendar.

The world converted to the Gregorian calendar in 1752. Otherwise different people around the world followed different calendars. Infact people who do agriculture and farming, still use a combination of solar and lunar calendars.

Who came up with the 12 month calendar?

The 12 months in the calendar, as we know them today, were first introduced by Julius Caesar, in the year 45 BC, on 1st January.

How many months were in the original calendar?

The calendar used previously consisted of 10 months. But it couldn’t account for the cyclic revolution of the earth around the sun, which takes exactly 365.2422 days.

The 10 month calendar

The previous Roman calendar, began the year in March and ended it in December. It had been in use from 753 BC, by Romulus, the legendary first king of Rome.

This calendar was later modified because it accounted for only 304 days in a year.

Who started the leap year?

The second king of Rome, Numa Pompilius added two months at the end of the calendar, Ianuarius and Februarius, to account for the missing days. He also introduced an intercalary month that occured after Februarius in certain years. These years became known as leap years. In addition, he deleted one day from all the months that had 30 days, so that they had 29 days instead.

Around for 700 years!

This resulted in a total of 355 days in a common year and 377 days in a leap year. The leap years were declared at the whim of the king. Although unstable, the calendar was in use for 700 years.

But it got very confusing because seasons and calendars did not match. It played havoc with the farmers.

So Julius Caesar, in 45 BC, under the guidance of his astronomers, decided to alter the calendar and make it more stable. Finally, the seasons had a chance to catch up!

For sixteen centuries!

When did we switch to the Gregorian calendar?

The same calendar had been in use since 1752, when the Gregorian calendar was adopted all over the world, to synchronise it to the English and American Colonies. The world and its boundaries had expanded quite a bit, from Caesar’s times! The Gregorian calendar fixed the Julian calendar error of calculating one revolution of the earth around the sun to take 365.2422 days, into account.

So, there you have it! It was originally Julius Caesar, who initiated the 12 months we have in the calendar today!

Alcohols, Phenols and Ethers

Remember sometimes you go to a petrol pump and smell the petrol? Or if someone is cleaning the bathroom they pour a liquid and the liquid has a smell to it? Or when you go to the doctor when you are hurt and they apply a solution that feels cool when it is put on your skin. These things may contain chemicals that are known in chemistry as Alcohols, Phenols and Ethers.

What is an organic compound?

An organic compound is any compound which contains a carbon atom. Most oils, petrol and diesel and most molecules in living things are organic compounds.

What is hydroxyl group?

A hydroxyl group is an Oxygen atom attached to a Hydrogen atom.

What are alcohols?

An alcohol is when the Oxygen of the Hydroxyl group is also connected to the Carbon of an organic compound. Many alcohols are produced when the fruit is left alone for a few days and the bacteria eat the sugar inside the fruit. They use the sugar for energy and produce a waste that is usually alcohol.

Classification of alcohols

Alcohols are classified depending on the number of carbon atoms they contain.

  1. Methanol
  2. Ethanol
  3. Propanol
  4. Butanol
  5. Pentanol
  6. Hexanol

General formula of an alcohol

The General Formula of an alcohol is C(n)H(2n+1)-OH
Where “n”- Is the number of Carbon atoms

5 Uses of alcohols

Alcohols are used in a variety of ways,

  1. Alcohols are used in disinfecting the skin of a patient when they are injured or are about to be operated upon.
  2. Alcohols are used as fuel.
  3. Alcohols are also used as antifreeze to stop liquids from freezing in winter.
  4. Alcohols can also be used at preservatives.
  5. Alcohol is used as a solvent to dissolve chemicals, creating perfumes and more.

What are phenols?

Phenols are aromatic compounds- which means that when you smell phenols, they will give off a fruity smell.
Phenols are six carbon atom arranged in a circle with a Hydroxyl group attached to one of them.

General formula of a phenol

The formula of a phenol is C6H5-OH

Uses of phenols

Phenols are used in many cleaning agents when you clean floors and bathrooms, they are excellent at killing bacteria.
Phenol is also used in the production of cosmetics such as sunscreen and hair dye.

What are ethers?

Ethers are two Carbon atoms connected by an Oxygen Atom. These two carbon atoms could be part of larger compounds as well.

General formula of a ether

The general formula of a ether is C-O-C

Uses of ethers

Ethers are very interesting molecules because of their peculiar structure. They are used in Aerosol sprays, High Boiling Solvents and as a part of cosmetics.

Examples of ethers

Ethylene Oxide, Anisol and Diethyl ether are examples of ethers.

Recording Daily Weather

Why is it important to record daily weather?

Weather forecasting has been an important part of traditions in all civilizations for thousands of years. Farmers wanted to know the weather conditions for their crops, merchants needed favourable weather to begin their sea-voyages and even the common man wanted to know how the weather would be in the future. Since there were no modern tools to predict the weather, everyone looked for the signs in nature. Most of the times, the ancient people banked on old mythological proverbs and religious faiths.

When did modern weather forecasting begin?

Few hundred years ago, a naval officer named Robert FitzRoy came up with the idea of predicting the weather. He was deeply troubled by the massive loss of life at sea because of the extreme and unpredictable weather. He decided to set up an office in London where he used some basic equipment such as the barometer, nautical charts, and recorded patterns to predict the weather. As the telegraph network expanded in 1830s, FitzRoy could gather weather data from different coasts at his London office. If he thought a storm was around the corner, he immediately released a warning telegraph to the concerned port where a drum was raised to alarm the sailors. Though he had to face a lot of ridicule and mockery from the society, he continued working on weather predictions. Finally, in 1861, his forecasts started getting printed daily in ‘The Times’ newspaper of London. The first ever daily weather forecasts were published in The Times on August 1, 1861.

How do meteorologists forecast the weather?

Meteorology is the study of weather and the atmosphere. A meteorologist is a person who studies weather patterns and predicts how the weather would be in the future. All of you would have seen a meteorologist, or weather person, talking about weather on the news channels. Meteorologists gather information about the weather from satellites, balloons, and other instruments. They use powerful computers to analyse the collected data, and then, draw weather maps to predict the weather.

What are the different gadgets to predict weather?

  1. A Thermometer measures the air temperature. Thermometers are plain glass tubes containing liquids such as alcohol or mercury filled inside them. When air around the tube heats up the liquid, the liquid expands and rises up the tube. The readings on the thermometer then shows what the actual temperature is.
  2. A Barometer is a scientific device used by meteorologists to measure air pressure. When the barometer readings shoot up, it indicates sunny and dry weather, and when barometer readings fall down, it indicates rain and stormy weather.
  3. A Sling Psychrometer measures relative humidity.
  4. A Rain Gauge measures the amount of rain fallen over a time-period.
  5. A Wind Vane is an instrument that tells the direction of the wind.
  6. An Anemometer measures wind speed.
  7. Weather Maps show atmospheric conditions over a large portion of the Earth’s surface.
  8. A Hygrometer is a scientific instrument to measure the humidity in the air.
  9. A Weather Balloon measures weather conditions high up in the atmosphere.
  10. Weather Satellites are used to photograph and track large-scale air movements taking place over the Earth’s surface from the space.

Why is weather forecasting important?

There are several reasons why weather forecasts are important. Weather forecasting is a Science, that impacts the lives of many people. It forewarns the people about the future weather conditions so that people can plan their activities accordingly. It warns people about the impending severe weather conditions and other weather hazards such as thunder storms, hurricanes, and heavy rainfalls. Thus far, accurate weather predictions have been able to save the lives of many.

Are weather forecasts always correct?

Well, there has been a significant development in the technology of weather forecasting over the last 20 years. The weather forecast stations of today are much better equipped to provide advanced warnings of severe weather and save lives of many, but they are not always accurate. There is a lot of scope for improvement. Accurate weather forecasting requires powerful computers and lots of observational data collected from land, sea and air. A single weather station does not have the equipment to collect so much information and any major weather forecast is made only after a careful study of data received from thousands of stations across the globe. The other thing is that it is hard to predict the weather, as weather patterns are always changing.

8 Interesting facts about weather forecasting

  1. The first ever daily weather forecast was published in ‘The Times’ on August 1, 1861.
  2. If you love Math and Science, you too, can be a perfect meteorologist!
  3. There are some very interesting old proverbs that you can use to predict weather.
  4. Red Sky at Night, Sailor’s Delight. Red Sky in the Morning, Sailor’s Warning. This saying was used to warn the sailors about the weather conditions at the sea. If the sky was red at night, a fair weather could be expected and if the sky was red in the morning, it was a sign of a storm.
  5. Clear Moon, Frost Soon. The idea behind this saying was that a clear moon in the night sky meant frost in the morning.
  6. Cows Lying Down, Weather on the Way. The ancient farmers believed that when cows lied down on the ground, it was a sign of stormy weather and rain.
  7. Count the Cricket Chirps, Tell the Temperature. This proverb meant that any increase in the number of crickets in the area was a sign of increasing temperature.
  8. Ring around the Moon, Rain Real Soon- This meant that if you spot a ring around the moon, it would rain soon.

Why cleaning your room is important?

Keep your room clean and organized!

We all have days when we feel a little dis – organised. But sometimes a few days of being dis – organised can become a bad habit. Soon, we start becoming messy, and start creating a messy environment around us. We misplace things or even allow them to get spoilt. What do you think? Would you like to visit a friend’s house and see a messy room. An unkempt bed, leftover food, or all their books all over the place. Obviously, no!

So let’s keep our rooms organised and clean. Because we like coming back to a clean room!

Coley: Why would you need binoculars in your own room Bumbley?
Bumbley: Don’t disturb me. I am trying to concentrate here.
Coley: Concentrate?? For what?
Bumbley: Can’t you see? I am looking for an assignment I need to submit in school today.
Coley: Oh okay. Wait. I am gonna ask again. Why do you need binoculars for that??
Bumbley: How else do I find it in here!
Coley: Keeping your room clean would be a better start, no?
Bumbley: I keep hearing this from mom. Now, you don’t start!
Coley: Okay.
Bumbley: No, wait! Help me find this assignment. It is very important for my school report.
Coley: I will. But on one condition. Start keeping your room clean.
Bumbley: I do try. But somehow it ends up being messy. How do I keep it clean??
Coley: By putting back every item where you took it from. That way you won’t create a mess to clean it up later.
Bumbley: Hmm..
Coley: Keeping things organized not only helps you find something when you need it, but also saves you time and lets you think with clarity.
Hey, I found your assignment!
Bumbley: Really? And I find you awesome!

Classification of Plants

How are plants classified?

Plants are autotrophs and can make their own food through photosynthesis. Plants are classified based on their genetic and evolutionary relationship and form one of the five major kingdoms of classification.

Who came up with the classification system of organisms?

Carl Linnaeus, father of taxonomy is credited with creating the current system of classification of organisms in use today. In classification, the binomial nomenclature system is used and is in Latin.

It is divided into :

  • Kingdom
  • Division
  • Classification Order
  • Family
  • Genus
  • Species

What are the two main groups of plant classification?

Plants are classified into two main groups. This is a very basic way of classifying them.

I. Non Vascular Plants

  • Non vascular plants are known or thought to be the earliest living plants on the planet. They lack vascular tissues and wood that can give them structural support. They also lack true leaves, stem and roots that can help them transport water and nutrients. Because of this they are limited to a narrow range of habitats. The most common type of non vascular plants include the phylum Bryophyta.
  • The Phylum Bryophyta is a diverse group with over 10,000 plant species and consists of mosses, liverworts and hornworts.
  • Despite lacking some essential plant organs, bryophytes play an important role in minimising erosion along water bodies, carrying out water and nutrient cycling in forests and regulating temperature in permafrosts.
  • They reproduce through spores.

II. Vascular Plants

  • Vascular plants posses vascular tissue (xylem and phloem) that help them to transport water and minerals. They are also known as tracheophytes.

Vascular plants are divided into three main Phylum :

1. Pteridophytes

This phylum consists of over 12,000 species and over two thirds of them are tropical and consist of species of ferns and fern allies.

  • Pteridophytes are seedless plants. They reproduce using spores on the underside of their leaves. These are known as sporophylls. They do not flower or have seeds or cones for reproduction.
  • Pteridophytes have horizontal stems called rhizomes and simple leaves roots. The leaves are called fronds and unroll at maturity.
  • Pteridophytes have adapted to a wide range of habitat. They can be aquatic terrestrial and even cold resistant, but thrive in tropical regions.

2. Gymnosperms

Gymnosperms are thought to be some of the oldest living plants on the planet and exist in temperate and arctic regions. Members of this Phylum include pines, hemlocks, firs and spruce. The name gymnosperms means naked seed, which is exhibited by the presence of cones (or strobili) instead of seeds.

  • Gymnosperms are characterised by wood and green, needle like foliage.
  • Gymnosperms are considered to be heterosporous, that is they produce both male cones and female cones.

3. Angiosperms

Angiosperms are referred to as the flowering plants and is the most diverse Phylum with over 300,000 species, including trees, herbs, shrubs, bulbs, epiphytes(parasitic plants) and plants living in both marine and fresh water habitats.

  • Angiosperms are vascular seed plants, in which the ovule (egg) is fertilised and develops into a seed in an enclosed ovary.
  • The flower carry either the male reproductive system or the female or both.
  • The angiosperms have a very complex vascular tissue system and have adapted themselves to almost all types of temperatures and regions. They have developed extensive root systems and leaves that help them to absorb nutrients and make food for themselves.
  • Angiosperms have localised regions for plant growth called meristems and cambia. These two regions experience cell division for the regeneration or repair of a plant.
  • Angiosperms maybe either monocot or dicots.

What is the difference between monocot and dicot plants?

Monocotyledons

Dicotyledons

1.

Monocotyledons or monocots have one cotyledon embryo.

Dicotyledons have two cotyledons embryo.

2.

The veins in the leaf are parallel

The veins in the leaf are netlike(reticulated)

3.

The vascular tissue bundles are arranged in a complex way.

The vascular tissue bundles are arranged in a ring.

4.

Fibrous root system

Deep tap root system

5.

Flowers parts in multiples of three

Flower parts in multiples of four or five.

6.

Pollen with a single pore

Pollen with three pores

7.

Secondary growth absent

Secondary growth present.

Examples of Monocotyledons

Banana, Orchid, Palm Tree, Sugar cane, Ginger, Onion, Rice, Wheat, Corn, Barley

Examples of Dicotyledons

Mangoes, Almonds, Beans, Peas, Pepper

Addition and Subtraction of Integers

What are Integers?

Integers are numbers that are not fractions such as 1,2,3… 45, 265 etc.
Fractions or numbers that also have parts of numbers are not integers.

For Example :
1.5, 2/3, ½, 23.21, 733.21 are not integers.

What do you do with Integers?

Integers can be added and subtracted to each other. They can also be divided and multiplied. But while doing so they have certain integer properties.

Properties of Integers

1. The Commutative Property of Integer Addition

If you are adding two or more integers to each other, they add up to the same answer, no matter what order you add them up in.
3 + 5 + 2 = 10
2 + 3 + 5 = 10
5 + 3 + 2 = 10
Each time it is the same answer!

2. The Commutative Property of Integer Multiplication

If you are multiplying two or more integers to each other, they add up to the same answer, no matter what order you add them up in.
3 x 5 x 2 = 30
2 x 3 x 5 = 30
5 x 3 x 2 = 30
Same answer each time!

3. The Associative Property of Integer Addition

Even if you group the integers in different ways and then add them, they will have the same answers.
(3 + 5) + 2 = 8 + 2 = 10
(2 + 3) + 5 = 5 + 5 = 10
5 + (3 + 2) = 5 + 5 = 10
And again, same answer!

4. The Associative Property of Integer Multiplication

Even if you group the integers in different ways and then multiply them – they will have the same answers.
(3 x 5) x 2 = 15 x 2= 30
(2 x 3) x 5 = 6 x 5 = 30
5 x (3 x 2) = 5 x 6= 30
Same answer!

5. The Distributive Property of Integer Addition and Multiplication

The distributive property of Integer Addition happens when you are multiplying integers with a group of integers you have added together. For example :
4 x (2 + 5) = ?
In this case, you have to follow the distributive law which states that each integer inside the brackets is multiplied to each integer outside the brackets.
So
4 x (2 + 5) = (4 x 2) + (4 x 5)
or
6 x (7 + 9) = (6 x7) + (6 x 9)

What are Positive Integers and Negative Integers?

Positive integers are all the integers that are greater than 0
+1, +2, +3, +4, …. +254 are all positive integers.
Usually when we write down positive integers we do not use the ‘+’ sign and this includes numbers in infinity.
Negative integers are all the integers that are less than 0
-1,-2,-3…. -254 are all negative integers

Rules for adding Integers

A positive integer when added to another positive integer is always going to be another positive integer.
(+4) + (+24) = (+28)
A negative integer when added to another negative integer will always result into another negative integer
(-13) + (-4) = -17

Rules for subtracting Integers

When a negative integer is subtracted from a positive integer, you need to change all the ‘-’ signs to ‘+’.
5 – (-6) =?
Does the sign change here?
– (-6) = + (+6)
Now use the same rules for addition :
So,
5 – ( -6) =
(+5) + (+6) = 11

Floatation and Relative Density

What is floatation?

Floatation is the phenomenon of any substance or object resting on the surface of a liquid, without sinking.

The following are some floatation examples :

  • A plastic bottle floats on water.
  • A piece of wood floats on water.
  • Oil drops floating on water.

Why does an object float?

An object floats because of the differences in density of the object and the medium which is mainly liquid.
If a substance is denser than a liquid, it will sink. If a substance is less dense than the liquid it is put into, it will float.

What is density of a substance?

Density is the weight of a substance per unit volume. You can define the density of water by saying how many kilograms a liter of water or kerosene or any other substance weighs.
Another way of calculating density is by looking at the Relative Density of a substance. Which defines how dense a substance is, compared to another substance.

For example :
Mercury is 13.6 times denser than water. So if one liter of water weighs roughly one kilogram, one liter of mercury would weigh 13.6 kilograms.

What is the formula for Relative Density?

The formula for Relative Density (RD) is :
RD = (Weight of any volume of a substance) / (Weight of an equal amount of water)

Example :
500 ml of citric acid (lemon juice) weighs 800 grams. If 500 ml of water weighs 500 grams. What is the relative density of citric acid?

Solution :
RD = Weight of 500 ml Citric Acid/Weight of 500 ml Water
RD = 800/500
RD = 1.6
The Relative Density of Citric Acid with respect to Water is 1.6

The Relative Densities of some common substances are given below :

Relative Density of Water 1
Relative Density of Soil 2
Relative Density of Mercury 13.6
Relative Density of Sand, 2.65
Relative Density of Silver 10

Antarctica's Shrinking Iceberg

Thousands of years ago, most of Europe, Asia, North and South America was covered by huge sheets of ice, each several kilometres thick, but today, the only ice sheets on the Earth are found in Antarctica and Greenland. In this article, we will talk about Antarctica. It is a continent at the South Pole, located at the bottom of the globe. The continent remains frozen throughout the year because of extremely cold weather. Scientists believe that more than 90% of the ice found on the whole planet is in Antarctica. Today, Antarctica is changing fast because of the ongoing climate change.

What is climate change?

Climate change is what happens when our actions affect the Earth’s atmosphere. Our indiscriminate usage of the earth’s resources have caused drastic changes in global temperatures and weather. You would have noticed that the summers are becoming warmer, with temperatures soaring as high as 50 degrees Celsius and winters too are becoming more unbearable than before. All of this is a result of climate change, and we are directly responsible for it.

What is global warming?

Global warming is the rise in the temperature of the Earth. The harmful gases that are released from the vehicles and factories go up into the air. These gases are known as greenhouse gases and some of these gases trap heat and make the whole planet warmer. Deforestation or removal of the green cover of the Earth also contributes to global warming. Global warming does not just mean one day of hot weather. It means a slow but steady rise in the temperature over many, many years. Deforestation also contributes to global warming.

Let us explain to you in a little more detail. The Sun naturally warms up the Earth through its atmosphere, and the excessive heat from the Earth is reflected into space. Generally, the temperature on the Earth remains perfectly regulated by its atmosphere, but the presence of too many greenhouse gases makes the atmosphere thick and causes a ‘green house’ effect. The excessive heat from the sunlight gets trapped within the Earth’s atmosphere, leading to a rise in temperature. The ice in Antarctica is not supposed to melt, but because of global warming, it is melting a little bit more every year.

What are icebergs and glaciers?

Glaciers are made up of a large chunk of snow and ice and are found in Antarctica. An iceberg is a piece of glacier that breaks off from it because of the rise in temperature. Icebergs are made of fresh water and can float on sea water.

Are icebergs breaking away from the glaciers in Antarctica?

According to a NASA satellite, a large iceberg broke off from the Antarctic glaciers in July 2017. If the icebergs keep breaking off from the glaciers and begin melting, this will lead to a noticeable and dangerous rise in the sea-levels across the globe.

What are the harmful effects of climate change?

Changes in climate lead to serious natural disasters such as cyclones, earthquakes and tsunamis. This will lead to flooding of the low-lying areas and loss of vegetation and wildlife. Some of the major U.S. cities like Boston, Miami and New York are more likely to be flooded first. Many islands near the South Pacific Ocean and the Indian Ocean will be buried under the water. The number of people displaced could be well-imagined.

Icebergs also act like a mirror; they reflect the sunlight and thereby help in keeping the Earth’s temperature under control. If they disappear, the Earth will become warmer and many harmful climate changes would take place.

You CAN Help!

You would be thinking that since the problem is so big, there is hardly anything that you can do to help, but this is not the case. Each one of you who is reading this article can help in preventing this crisis.

Here is your list of do’s and don’ts to reduce climate change

  • Remember the three Rs-Reduce, reuse, recycle. Reduce the use of non-renewable fuels and things that consume more power. Try to reuse your old things. You can also give away your old clothes and toys to the needy children. Be creative, make an effort to come up with ideas to make new things out of the old. Try to put everything back into use.
  • Plant more trees.
  • Use energy saving CFLs in your house instead of bulbs and tube lights.
  • Use electrical appliances in your home wisely.
  • Turn off the lights and electrical appliances when not in use
  • Save water in the washroom.
  • Instead of going out in your car, prefer to use your cycle, or any means of public transport.
  • Let us prevent any further climate change, reduce our carbon footprint and adopt an eco-friendly lifestyle, starting TODAY!

Fact sheet on climate change

  1. As per the scientists, the global sea level rise has increased from 2.2mm each year in 1993, to 3.3mm each year in 2014.
  2. The average global temperature on the Earth has increased about 0.8° Celsius (1.4° Fahrenheit) since 1880.
  3. According to a research study, global warming will increase the Earth’s average temperature by 2-11 degrees Fahrenheit by the year 2100.
  4. Small icebergs weigh hundreds of tonnes and the big icebergs may weigh about billions of tonnes.
  5. Smaller icebergs are known as bergy bits and growlers. They are especially dangerous for ships because it is difficult to spot them.
  6. The famous ship Titanic sank after hitting an iceberg.
  7. Greenhouse gases mainly comprise of carbon dioxide, methane, nitrous oxide and chlorofluorocarbons (better known as CFCs).

Discovery of Ink

Human beings as they evolved from prehistoric ancestors, developed many forms of communication. One of the most important tools discovered by humans, has been written communication.

He first wrote on cave walls and then stone and developed a pictorial vocabulary. As time progressed, shapes and sounds were incorporated in the written form. The earliest surviving texts from Mesopotamia dating back from 2100 BC, were written with reeds or stylus on clay tablets. These show that by then, man had developed an evolved form of writing and communication.

History of ink

It was the Chinese who are credited with first discovering ink 5000 years ago. It is still being used in that form. The liquid India Ink we use today was also discovered by the Chinese. The ink was thus named because the carbon black that was used to make the ink was sourced from India. It was the Cao Wei Dynasty (220 AD – 265 AD), who established the manufacture of India Ink.

Ink and how it is used has evolved over the years, changing colours and composition to adapt it to different needs.

History of Renaissance

What does Renaissance mean?

The Renaissance was a period in European history from the 14th century to the 17th century. The word Renaissance means rebirth. It was a rebirth in the sense that the period was a connecting period between the Middle Ages and Modern Ages in European history, though it is closely associated with Florence, Italy.

Why is the Renaissance important?

The Renaissance is important because it signalled the beginning of change in the thinking of European Christianity and so the perception of Man, Church and God changed too. This changed art, literature and architecture also.

The seeds of Renaissance were sowed post the Black Death, the plague which wiped out millions of people in Europe, between 1346 and 1353. This caused the economy to change as well.

Why did the Renaissance start?

The Rennaisance started with the decline in the powers of the Roman Catholic Church. The humanists emerged who believed that individuals had important contributions to make in the world, rather than that, the only ideas were of the Church.

How did Renaissance affect science, arts and literature?

  • During Renaissance, science, arts, architecture, philosophy and literature underwent a transformation in techniques and thought. Man became the measure of all things, as earlier stated by the Greek Philosopher Protagoras(490 BC to 420 BC). Some of the Renaissance thought patterns did reflect the early Greek and Roman philosophies. Renaissance art and philosophies brought human emotions into focus.
  • Renaissance art did not reject Christianity. However, there was a subtle shift in how intellectuals approached religion and other cultural areas of life. Printing was also discovered during this period.
  • During the Renaissance, art and money went hand in hand. The church was one the patrons apart from wealthy noblemen, who were businessmen.

Leonardo da Vinci’s contribution to the Renaissance period

Leonardo da Vinci’s brilliance crossed multiple disciplines, that he was referred to as the Renaissance man. Apart from the Mona Lisa and The Last Supper, two works of art he is famous for, he also did extensive studies and invented various machines and also surgery.

Leonardo da Vinci also created the map of the anatomical proportions of the human body, a very important study based on the notes of the architect Vitruvius. The defining of man as the measure of all things, the essence of Renaissance is reflected in this.

The Renaissance Timeline

  1. 1346   Bubonic plague begins
  2. 1350   Renaissance begins
  3. 1413   Brunelleschi creates Linear Perspectives in Art
  4. 1429   Joan of Arc and the Siege of Orleans

Helen Keller was determined to communicate with others and she learned to speak. She spent much of her life giving lectures and speeches. She learned to read lips with her finger tips, so she could ‘listen’ to other people’s speeches.

She is known for her strong support for people with disabilities. She travelled to over 25 countries, giving lectures and motivational speeches about deaf people’s conditions.

Political and Social Activism

Apart from this, she was a woman’s rights activist, a political activist, a social activist and a pacifist. She also helped set up several foundations for the various causes she believed in, like the Helen Keller International organisation, along with George A Kessler, and it is devoted to research in vision, health and nutrition.

Nuclear Fission and Nuclear Fusion

Nuclear Fission and Nuclear Fusion are reactions which convert matter into energy.

What is matter?

The world you see around us has many things and all of this is made up of matter. Matter is anything and everything in the universe that occupies space.

What is the relationship between matter and energy?

The matter is made up of energy. Energy is what makes us do work.

What is nuclear fusion?

  • When matter fuses together to release energy, that is nuclear fusion.
  • All matter is made up of molecules, molecules are made up of atoms and atoms have a nucleus and electrons.
  • The Sun produces sunlight through nuclear fusion.
  • Inside the sun- where it is very hot, the nucleus of one atom and the nucleus of another atom come together and become one. A little bit of matter is left out- that little bit of matter is converted into a lot of energy.

What is nuclear fission?

  • Nuclear Fission is the process through which energy is created in nuclear power plants. It is also how nuclear bombs work.
  • In nuclear fission, the nucleus of an atom breaks into two or more nuclei (plural for nucleus). When the nucleus breaks, some matter is lost, this small amount of matter is converted into a large amount of energy. These broken nuclei then go and bombard other nuclei , those nuclei then break into more nuclei and this process can go on and on releasing a tremendous amount of energy.

Don't Litter, Make The World Better!

Imagine it’s a beautiful summer day, and you’re out with your friends for milkshakes in the park. You finish your milkshake and look around, but there’s no trash can for your empty cup. It’s okay to just leave it underneath the park bench, right? Nobody can even see it under there, and you want to go play baseball. You don’t want to carry around this gross, sticky milkshake cup.

You might think it’s okay, but it’s not. Leaving your empty milkshake cup under the bench is littering.

What is littering?

All of you must have seen the bits of wrappers, packets, plastic bags lying all around when you go for a walk, or step outside your home. That is litter. Sometimes in small quantities it is just simply annoying. But when you have huge quantities of it, it becomes garbage and causes landfills.

Landfills, not only become eye sores but also places which become breeding places for disease causing animals and pollute the environment.

What are the effects of litter on the environment?

The litter often finds its way into drain holes and waterways, choking them. It is also carried away into our water resources, in the rainy season. Our rivers and oceans become polluted causing animals and plants to die in the water.

You must have also seen animals unknowingly eating bits of paper, or plastic thinking it is food. This harms them.

Why cleaning up our litter is expensive?

  • Sometimes when we knowingly or unknowingly throw litter, we don’t realise it might become inconvenient for someone to clean it up later. Although in cities, there are people who do go about cleaning, sometimes it is delayed. It is also expensive.
  • Every year, a city’s administration spends lots of money to clean up the city on a daily basis and dispose it off. Some of our litter is biodegradable and some of it is not. And lots of people spend time and energy to make sure our cities and town are clean and healthy for us to live.

What is Antarctic Circle?

The Antarctic circle is depicted as a red line at the bottom of the globe. It is actually an imaginary line placed to the south of the Equator.

Where is the Antarctic Circle located?

This special line of latitude is approximately 66¹/₂ degrees south of the equator and outlines the chilly southern zone of the world.

What’s inside the Antarctic Circle?

The continent of Antarctica lies within the Antarctic Circle. Antarctica is bigger than Europe and almost double the size of the continent of Australia. It remains covered in 99% ice almost throughout the year and because it experiences hardly any rain, scientists often refer to it as a desert. Antarctica has very little flora and fauna to boast of because of the harsh climatic conditions, but you would find some interesting animals such as penguins, whales seals, albatrosses, skua, snow petrel and krill.

Why is the Antarctic Circle important?

It helps the scientists in the study of the seasonal behaviour of the sunlight. It shows direct and indirect angles of sunlight.

What countries are in the Antarctic Circle?

There are no cities or villages in Antarctica. However, the countries nearest to the Antarctic circle are South Africa, Australia, New Zealand, Chile and Argentina.

What oceans does the Antarctic Circle touch?

Only the Southern Ocean passes through the Antarctic circle.

6 Interesting facts about Antarctic Circle

  1. The name ‘Antarctica’ comes from a Greek word meaning ‘opposite to the north’.
  2. The coldest temperature ever recorded on the Earth was in Antarctica on July 21, 1983, when it dipped 128 degrees below zero!
  3. All areas in the Antarctic Circle have twenty-four hours of daylight on the Summer Solstice in December.
  4. All areas in the Antarctic Circle have twenty-four hours of night in June on the Winter Solstice.
  5. The South Pole is in the center of the Antarctic Circle.
  6. There is no permanent population on the Antarctic Circle. Different countries have their research centres based in Antarctica where their team of scientists stay for some time of the year and conduct research.

Ratio and Proportion

What is a ratio?

Ratio is a relationship between two numerical values. It shows how many times one value contains another value.

Examples of ratio

When we make mango crush, we are told to add one part crush to four parts water. Which means if I take one cup of crush, I need to add four cups of water. This is a relation that can be written as 1:4.

How to solve ratios?

Sam wants to make tea with the ratio of milk to water to be 2 : 3. If he needs to make 5 cups of tea, how much milk and water will Sam need?

Answer – Sam needs a ratio of 2 : 3, thus the total parts of his mixture are 2 + 3 = 5. Since he is making 5 cups of tea, 1 cup can be said to be equal to one part.

Milk has to be 2 parts out of 5 so Sam will need 2 cups of milk.
Water has to be 3 parts out of 5 so Sam will need 3 cups of water.

What is a proportion?

Proportion is used to describe how much of a certain component is there in something. Like our mango crush will always be one part of crush and four parts of water. Thus there is a total of 5 parts in our crush. So mango crush will always be one part out of five and thus ⅕.

Types of proportion

1. Direct proportion

In the case of our crush, if we take one cup crush, we need to add four cups water. If we take two cups of crush, we will have to add eight cups of water. Thus if the quantity of one proportion increases, the quantity of the other also increases. This is called Direct Proportion.

2. Indirect proportion

If the quantity of one value increases, the other goes down, and vice-versa. This relationship is called Indirect Proportion.

Examples of proportion

In some cases like in a race, the relation between speed and time taken to cover a specific distance is proportional but not directly.

If we are travelling at 20 km per hour, we will cover 20 kilometer in one hour.
If we are travelling at 40 km per hour, we will cover 20 kilometer in half an hour.

As you can see, if the quantity of one value increases, the other goes down.

Proportion formula

If a:b::c:d then a/b=c/d

How to solve a proportion

If a car travels 30 km in one hour, then how far will it travel in two hours?
Answer – Let us assume the car travels Z km in two hours.

By the formula of proportion-
30km : 1 hour = Z km : 2 hours

So 30/1= Z/2

Z= 30/1 x 2

Z = 60

Thus the car will travel 60 km in two hours.
